Preferably the outward upper ends of the ribs i6, H are connected by a transverse wall or closure 20 formed also integrally with the ribs i6, i1 and the side frame, the elements 86, H and 20 providing means for confining the end of a brake beam on three sides, in case the beam is to be guided upon the side frame. As in my aforesaid application the tension member I2 is preferably provided with a relatively narrow bottom reinforcing portion 2| extending under the Window opening of the side frame. And also as therein disclosed the hollow tension member is reinforced by a vertical interior web 22 as in Fig. 4 herein, but in the present case this web extends not only within the upwardly inclined portion of the tension member, but along the deepest part thereof, underneath the window opening, as shown in Fig. 5. A reinforcing bracket 23, as shown in Fig. 5, preferably extends down from the spring seat l4 along the corresponding inner side wall of the tension member i2.

A pin or gate 24 is located at the lower inner ends of the ribs orflanges I6, I], and the same preferably passes downwardly through the inwardly projecting portion of the spring seat l4 and through the lower end of the rib H which is beneath the spring seat. Such pin or gate 24 is removable at will and when in position, as shown in Fig. 1, acts as a stop to prevent the dislodgement of the brake beam and the falling thereof on the track. This stop 24 when in the form of a pin may have the head thereof resting upon the spring seat and have a cotter pass claims herein characterize the stop as movable,

through the end thereof which projects beneath the rib H. i

It is to be distinctly understood that where the that it is the intention thereby to include a. stop whether it is entirely removable, from the side frame, as is the disclosed pin or gate '24, or is just sufiiciently movable to merely open up the.

mouth of the.guiding groove or means so that the end of a brake beam may be disen aged, or sufiiciently movable to interrupt and interfere with the disengagement of the beam. It is obvious'that if the gate or pin 24 is raised, it does not have to be removed from the upper hole in the spring seat in which it is inserted, in order to perform its necessary functions with respect to the end of the brake beam.

Preferably, as shown in Figs. 3 and 4 the recess I5 defined by the ribs I6, I! is lined by a wear sheet or plate 15a, l5b ofhardened steel as in my aforesaid application, and to prevent the same, when inserted in. the recess, from sliding in the direction of the inner ends of the ribs I6, II, the latter are provided with thickened portions 25 at their corresponding inner surfaces, which results in inward shoulders 26 with which the lower end of such a lining will .be engaged so as to prevent the same from sliding down longitudinally.

can be removed whenever desired. Should it be desired at any time when convenient to remove the stop or gate 24, the same can be done, and if the brake beam is disconnected from the brake mechanism, it maybe allowed to fall through the mouth 21 and onto the track. When repairs have been made or a new beam is to be used, the beam can be replaced readily by passing its ends into the mouths, such as 21, at the bottom of the side frames and then be moved up to proper position for travel upon the guide ribs I6, I I, the stops or gates 24 being then reapplied to they side frames so as to prevent the brake beam from falling to the track. It will readily be seen that the brake beam with the brake heads mounted 'thereon can be removed when dismounting the brake heads therefrom. This'also facilitates repair and replacements.

It will be obvious to those skilled in the art that desirable changes and modifications of the invention may be resorted to without departing from the scope of the appended claims.

What I claim as new is:

1. A car truck side frame having a spring seat, and including means thereon for supporting and guiding a brake beam upon the side frame, such means extending inwardly towards the center of the side frame along a line which passes beneath the entire spring seat and there terminating to permit the downward removal of the beam.

2. A car truck side frame having a spring seat, and including means thereon for supporting and guiding a brake beam upon the side frame, the longitudinal axis of such means extending inwardly towards the center of the side frame along a line which passes beneath the spring seat, and such means having a stop at its inner end to prevent removal of the beam, and movable at' guiding a brake beam upon the sideframe, the

longitudinal axis of such means extending inwardly towards the center of the side frame on a line which passes beneath the spring seat and on a downward angle of inclination so that the line of movement of the beam intersects .the car wheel axis. v

4. A car truck side frame having a spring seat, and including a brake beam supporting and guiding rib or flange thereon, extending inwardly towards the center of the side frame along a line passing beneath the entire spring seat.

5. A car truck side frame having a spring seat, and including a brake beam supporting and guiding rib or flange thereon, extending inwardly towards the center of the side frame along a line passing beneath the spring seat, and a beam limiting stop located at the inward end of the rib and movable at will when desired to permit removal of the beam.

6. A car truck side frame having a spring seat, and including a brake beam supporting and guiding rib or flange thereon and extending inwardly towards the center of the side frame along a line passing beneath the spring seat and stop means associated with the rib, for limiting the inward movement of the beam upon the rib the stop being movable at will when desired.

7. A car truck side frame having a spring seat, and including a brake beam supporting and guiding rib or flange thereon and extending inwardly towards the center of the side frame along a line 1 passing beneath the spring seat, and a stop en- 10 a beam upon the rib, the stop being movable at ing rib or flange thereon and extending inwardly towards the center of the side frame along. a line'passing beneath the spring seat, and a stop upon and projecting downwardly from the spring seat, for limiting the inward movement of the will when desired.

9. A car truck side frame having a tension member, and including a brake beam supporting and guiding rib or flange on the-tension member,

extending at an inclination downwardly to a' point between the top and bottom of the extreme lower portion of such member, which portion is below the bolster window opening, and the rib continued as far as such point. I

10. A car-truck side frame having a tension member, and including a brake beam supporting and .guiding rib or flange on thetension member,

extending .at an inclination downwardly to a' means below the rib and seat allowing access to the beam to-remove it.

12. A car truck side frame having a spring seat projecting inwardly thereof, and including a brake beam guiding rib on the inner side of the frame, extending therealong as a substantial continuation of the inward projection of the spring seat, the length of the rib being at least sufficient to guide the beam in its movement in a plying and releasing the brake.

14. A car truck side frame, including means for confining one end of a brake beam during brake application, such means supporting and guiding the beam along the frame towards the center thereof, the inner portion of such confining movable to permit lateral insertion of such end of the beam onto the confining means and the lateral separation of such end therefrom.
